V-delete-remote-dns-host return error

Good afternoon guys!
Peace and goodness to everyone!

It seems I don’t understand something, this is what I do according to the instructions, one thing is bad. An error is returned.
Now I want to add a dns cluster on the slave server.

v-add-remote-dns-host 'slave-dns-host' 8083 admin 'password' api 'dns-user

The console command shows the DNS slave server has been successfully added
v-list-remote-dns-hosts json
but the records on the DNS slave are not updated.

Previously, the cluster was hosted with another server, and now there are two of them.
And I want to delete one.

v-delete-remote-dns-host HOST

The delete command is frozen
Recording an error in the log /var/log/hestia/error.log
2024-04-18 00:06:18 v-delete-remote-dns-host [Error 1]

And now I can’t remove any remote-dns-host from the cluster

Please tell me what I’m doing wrong.
Please direct your thoughts into the course of correct reasoning.

Very grateful
